What Three Spotted Dwarf Rasbora look like
Boraras micros, commonly known as the Three Spotted Dwarf Rasbora, exhibits a diminutive, laterally compressed body, reaching a maximum adult size of approximately 2.5 cm (1 inch). The species is characterized by its translucent golden body adorned with three distinct dark spots, which are strategically positioned along the lateral line, enhancing its visual appeal. Sexual dimorphism is subtle, with females typically exhibiting a slightly fuller abdomen when gravid. Defensive adaptations include its small size and schooling behavior, which helps reduce individual predation risk. Notably, the species lacks an adipose fin, a feature common in many cyprinids, and possesses a small, terminal mouth with fine, pharyngeal teeth adapted for its omnivorous diet. The fins are delicate and transparent, further contributing to its ethereal appearance in the aquarium setting.
Behavior & temperament
The Three Spotted Dwarf Rasbora is a social, schooling fish that thrives in groups of six or more, exhibiting a peaceful temperament. It primarily inhabits the mid to upper water column, where it forages and interacts with conspecifics. This species is known for its active and curious nature, often darting about in the tank. Breeding behavior involves egg scattering, with females releasing adhesive eggs among fine-leaved plants or substrate. The species displays minimal aggression, making it suitable for community tanks, although it may become shy in the presence of larger or more boisterous tankmates.
Diet & feeding
In the wild, Boraras micros feeds on a varied diet consisting of small invertebrates, algae, and detritus. In captivity, it thrives on a diet of high-quality micro-pellets, finely crushed flakes, and live or frozen foods such as daphnia and brine shrimp to ensure proper nutrition.
